Van Oord has completed the final monopile installation for Dutch wind farm Hollandse Kust, bringing the number of turbine foundations to 70.
The wind farm should generate up to 760MW, which over a year will equate to 3.3TWh.
Weighing between 788 and 960 tonnes, the monopiles have been installed in record time, with the first only completed four months ago, in October.
“During the installation works CrossWind and Van Oord promoted and maintained an open culture, in which we acted as one team. I am convinced that this approach defined a big part of our success in reaching this milestone in a safe and timely manner,” said Wybren de Vries, Balance of Plant Package manager at CrossWind.
As well as working on the monopiles, for which Van Oord deployed DEME’s jack-up vessel, Van OOrd also designed, engineered, procured and installed the inter-array cables. Offshore installation vessel MPI Resolution was used to install secondary steel to complete the foundations, which consists of boat landings, main access platforms with davit cranes and internal platforms. These will be used for maintenance activities once the wind farm is operational, when Van Oord’’s cable-laying vessel Nexus will be deployed to install the main cables.
The Hollandse Kust wind farm is part of the Dutch government’s plan to generate 21,000MW of electricity across eight wind farms by 2030, which will equate to a 10-fold increase in offshore wind for the Netherlands.
